Description
The Flashlight Fish is a nocturnal marine fish known for its unique bioluminescent organ located beneath each eye, which houses symbiotic bacteria. This organ can be 'blinked' using a specialized shutter, used for communication, attracting prey, and evading predators. They require a dark environment with plenty of hiding spots and are best kept in a species-specific tank or with very peaceful, nocturnal tankmates.
